DAO-12

The DAO-12 is basically the combination of a revolver and a shotgun. The drum magazine moves in place like a revolver. All Shotguns in Battlefield 3 use the 12 Gauge 00 Buckshot cartridge by default, effective at close range.

The DAO-12 is a close range powerhouse, able to decimate enemies with it's large magazine size and quick firing rate. With a standard 8 round magazine, it allows for a wall of lead to fire out in front of the gun. But these 8 rounds can be expended quickly, forcing the player to reload, a slow process due to the fact that each shell can only be loaded into the gun one at a time.
